Subaru EJ25



This Flat 4 engine found on impreza's. 2.5 liter engine is capable of over 500whp+ and famous swaps on 911 and VW Beetle's

Nissan CA18DET Engine



This motor is known for stronger torque characteristics, as well as faster spool at lower RPMs. Many tuners are now converting the engine to a CA18DERT, which is the CA18DET with a supercharger bolted on. There was never a factory-produced twin-cam CA 2.0L motor, nor a turbo version. However the blocks are similar, and it is possible to fit the DOHC CA18DE/T twincam head to the SOHC CA20 block. However the DOHC/SOHC manifolds are different and the timing pulley/belts are not compatible. Despite this, CA20DET turbos have been built. BUT I DON'T LIKE IT!!

Nissan E1.5T SOHC



only with a displacement of 1.5L and 8valves the e15E engine will be a Japanese classic for its light and 300whp+ capabilities!

And eating head gaskets for breakfast...

Sorry, the EJ25 isn't the best Subaru engine. Their reliability track record is sketchy at best. You could make a case for the EJ20T or the EJ22 (the latter is a common swap in VW's also). Heck I'd even accept arguments for the EA81 or MPFI nonturbo EA82 because of how you can abuse the living crap out of them and they'll still run (even if they're not good modding engines).

Cast iron block and good head flow makes this engine a great rival for the 4g63
